“…The main chemical composition of the composites (Table 1) depends on the composition of the initial glauconite, which has already been shown to have a positive influence as a mineral fertilizer [44,46]. The produced glauconite-urea complex fertilizers can serve as a source of exchangeable P, Ca, and Mg [46]. Preservation of the chemical composition and microcrystalline form of nitrogen according to SEM prevent the decomposition of urea or its complete amorphization during mechanochemical activation with glauconite.…”

“…Glauconite (K 0.65-0.69 Ca 0-0.05 (Fe 1.46-1.59 Mg 0.26-0.30 Al 0.11-0.31 ) 1.96-2.06 (Si 3.48-3.66 Al 0.34-0.52 ) 4 O 10 (OH) 2 according to scanning electron microscopy (SEM) energy dispersive X-ray spectroscopy (EDS) data [46]) was collected from the Upper Cretaceous rocks of Slavgorod and Gan'kino formations of the Bakchar deposit in Western Siberia [46]. The technology to enrich glauconite concentrate (with a proportion of glauconite up to 95%) is outlined in Rudmin et al [44,45] as follows: wet sieving with a fraction between 80 and 500 µm and electromagnetic separation at a current of 3.5 A on an elctro-magnetic separator (EMS) 10/5 (JSC Mining Machines, Russia).…”

“…Glauconite is potassium phyllosilicate (clay mineral) with a dioctahedral structure [29][30][31][32] distributed in ancient marine sediments [33][34][35][36][37][38]. Due to the high content of K 2 O (up to 8-9%), glauconite can serve as an independent unconventional potash fertilizer [39][40][41][42][43][44][45] that has a prolonged effect [46]. The aim of this research was to study the mechanochemical methods of intracalation of urea into glauconite to synthesize a polyfunctional SRF using planetary and ring mills.…”

We investigated the mechanochemical synthesis of complex slow release fertilizers (SRF) derived from glauconite. We studied the effectiveness of the mechanical intercalation of urea into glauconite using planetary and ring mills. The potassium-nitric complex SRFs were synthesized via a mechanochemical method mixing glauconite with urea in a 3:1 ratio. The obtained composites were analyzed using X-ray diffraction analysis, scanning electron microscopy, X-ray fluorescence analysis, and infrared spectroscopy. The results show that as duration of mechanochemical activation increases, the mineralogical, chemical, and structural characteristics of composites change. Essential modifications associated with a decrease in absorbed urea and the formation of microcrystallites were observed when the planetary milling time increased from 5 to 10 min and the ring milling from 15 to 30 min. Complete intercalation of urea into glauconite was achieved by 20 min grinding in a planetary mill or 60 min in a ring mill. Urea intercalation in glauconite occurs much faster when using a planetary mill compared to a ring mill.

“…Glauconite is a potassium-containing dioctahedral phyllosilicate [ 66 , 67 ] that has recently been examined as a urea inhibitor in CRF [ 43 , 57 ]. At the same time, glauconite and glauconite rocks improve soil fertility and plant growth [ 46 , 68 , 69 , 70 , 71 , 72 , 73 , 74 ], making it possible to evaluate them as promising composite materials in the creation of modern multifunctional fertilisers.…”

This paper studies the chemical and mechanochemical preparation of glauconite with ammonium dihydrogen phosphate (ADP) nanocomposites with a ratio of 9:1 in the vol.% and wt.%, respectively. The methods include X-ray diffraction analysis, scanning electron microscope with energy-dispersive X-ray spectroscopy, transmission electron microscopy, infrared spectroscopy, and differential thermal analysis with a quadruple mass spectrometer. The manufactured nanocomposites keep the flaky glauconite structure. Some glauconite unit structures have been thickened due to minimal nitrogen (ammonium) intercalation into the interlayer space. The globular, granular, or pellet mineral particles of nanocomposites can be preserved via chemical techniques. Globular and micro-aggregate particles in nanocomposites comprise a thin film of adsorbed ADP. The two-step mechanochemical method makes it possible to slightly increase the proportion of adsorbed (up to 3.2%) and intercalated (up to 6.0%) nutrients versus chemical ways. Nanocomposites prepared via chemical methods consist of glauconite (90%), adsorbed (1.8–3.6%), and intercalated (3.0–3.7%) substances of ADP. Through the use of a potassium-containing clay mineral as an inhibitor, nitrogen, phosphorus, and potassium (NPK), nanocomposite fertilisers of controlled action were obtained. Targeted and controlled release of nutrients such as phosphate, ammonium, and potassium are expected due to various forms of nutrients on the surface, in the micropores, and in the interlayer space of glauconite. This is confirmed via the stepwise dynamics of the release of ammonium, nitrate, potassium, and phosphate from their created nanocomposites. These features of nanocomposites contribute to the stimulation of plant growth and development when fertilisers are applied to the soil.

“…Experiments with bentonite additives improved the performance of sandy and sandy loam soils and increased the yield of corn and millet grains [17][18]. The addition of glauconitolite significantly increases the yield of wheat, corn, oats, and beetroot [19][20]. Successful studies have also been conducted in various countries using diatomite, palygorskite, and bentonite clay for corn, wheat, potatoes, and mustard growing [21][22].…”
